Windows 7: Erratic HDD speeds, SMART error. Lemonade anyone?

Erratic HDD speeds, SMART error. Lemonade anyone?

Hi all!!!

To make a long story short, I was being spammed by BSODS and lockups on my primary HDD, and in the end I decided to back it up to my external and retreat to my backup drive. FYI, the BSOD's were 'Kernal-power' errors. I also noticed a massive slow down.

In the end I cloned my back up HDD to my primary HDD, and have run some HDTunes tests on the primary HDD since.

Although no errors in windows yet, the HDtune graph is very erratic, the timeline trail nosedives all over the place. My lowest read speed is about 19/ms whereas my highest is 147mbs. Also SMART is reporting C7 count 1 (Ultra DMA CRC error) In comparison, on my back up hdd the timeline trail is very smooth starting from the start to the end of the drive.

Is the ship sinking?
Thanks!

Can you try entering System Recovery and run chkdsk from command prompt?

Oh yeah forgot to mention I've run chdisk and a battery of HD tests and diagnostics using the boot cd and it all comes out fresh and dry.

Do you mean as in to make it safe to dispose of?

Else

When I made it a clone, I think it got pretty formatted during the process?

Ultra DMA CRC error means you have a bad sata cable, replace it for a new one and see if it makes the disk work as it should.
